Lets see the American Revolution, War of 1812, Chinese Opium War, Domination of India, Subjugation of Africa, Brutal Repression of the Irish and must I go on?
Hate to tell you this, but Britain, up until the first world war, still had a 'feudal' system within the army, based on units from different areas around the country.
Scottish Highlanders, Durham light infantry, Leicester light armoured division, the list goes on.
Infact, up until only a few years ago, there was a town in Cumbria who were still at war with Germany, because there their Malitia refused to sign the treaty after the first world war.
As in every country, it acted as one when the country was under threat, or there was a war to be faught.
BUT if you want to talk about specifics and then generalise them, then I suggest that you get your facts right and then start bringing another country into it to try and back up your vitriol.
Lets have a look at some of those you sited shall we?
Chinese Opium War, The East India Company.
Domination of India, try the East India company.
(Take your pick on which one you want to blame there, they all had their fingers in the pie, the Dutch, French, Portugese, Danish and British all had settlements in India)
Subjugation of Africa, lets hear it for the Dutch, British, French and Belgiams, if you notice 'pigeon' English and Africans has a distinct none 'British' accent to it.
Brutal Repression of the Irish, oh dear........the British Army influence was only placed there on the request of the Protestant Irish who were afraid that, as they were a minority, they were going to be victimised and that is only 'recent' history, try wandering back into the 15th century for the rest of that history when Irsih landowners began to sell off the lands to the British.
Now all of these were influenced by the British and very much so, though started by the millitery?
No they were influenced by big business, they were not started as Millitery actions.
